Map of Particle & Quantum

Deeper than the atom — nuclei & quarks, radioactivity & fission–fusion, and the strange quantum world: orbitals, wave–particle, tunneling, entanglement.

≈ 10⁻¹⁵ m · nucleus → elementary particle

Nucleus Hạt nhân & Quark

Protons/neutrons made of quarks (the strong force), the Standard Model of elementary particles and nature’s 4 fundamental forces.

Radioactivity Phóng xạ & Hạt nhân

α/β/γ decay, half-life, and nuclear energy: fission ↔ fusion.

Quantum Thế giới Lượng tử

Electron orbitals, wave–particle duality, tunneling and quantum entanglement.

Open simulation →

Antimatter Phản vật chất

The positron, annihilation → gamma photons, pair production (E=mc²), PET applications, and the mystery of why the universe is all matter.

Open simulation →

Particle Accelerator Máy gia tốc hạt

The LHC ring smashing particles near light speed → particle showers, detectors, hunting new particles like the Higgs (energy → mass).

Open simulation →

Entanglement Rối lượng tử

Two entangled particles: measure one and the other instantly correlates — violating Bell’s inequality WITHOUT sending information faster than light.

Open simulation →

Tunneling Hiệu ứng đường hầm

A wave packet ‘tunnels through’ an energy barrier even without enough energy — the basis of alpha decay, the STM and reactions inside stars.

Open simulation →

Spin Spin & Stern–Gerlach

A beam of atoms through a non-uniform magnetic field splits into exactly 2 lines — evidence of quantized spin (½), not a continuous band.

Open simulation →

Standard Model Mô hình Chuẩn

17 elementary particles: 6 quarks, 6 leptons, force bosons & the Higgs — the periodic table of matter. Click a particle for details.

Open simulation →

Wavefunction Hàm sóng & Hộp thế

A particle in a potential well: discrete energy levels, the wavefunction ψ with nodes and |ψ|² = where the particle is likely found.

Open simulation →

Black-body Radiation Bức xạ vật đen & Planck

A hot body emits a spectrum that shifts toward blue as it gets hotter. The ‘ultraviolet catastrophe’ forced Planck to quantize energy — the birth of quantum physics.

Open simulation →

Photoelectric Effect Photon & Quang điện

Light ejects electrons only when the frequency is high enough, no matter how bright — evidence that light is photons E=hf (Einstein, Nobel Prize).

Open simulation →

Uncertainty Principle Nguyên lý bất định

The more precisely you pin position, the blurrier momentum (Δx·Δp ≥ ħ/2) — not clumsy measurement but the wave nature of everything.

Open simulation →

Superposition Chồng chập & Mèo Schrödinger

A particle can be in many possibilities at once until, measured, it ‘collapses’ to one result. Schrödinger’s cat is the famous metaphor for that paradox.

Open simulation →

Matter Waves Sóng vật chất de Broglie

Everything in motion has a wavelength λ=h/p — an electron’s is large enough to diffract like a wave, while a human’s is far too small to see.

Open simulation →

Four Fundamental Forces Bốn lực cơ bản

Strong, electromagnetic, weak and gravity, the four forces that build the universe. Strengths differing by trillions, range, carriers, the dream of unifying them.

Open simulation →

Neutrinos Neutrino & Dao động vị

A ‘ghost’ particle passing straight through Earth and our bodies; in flight it changes flavor (νe↔νμ↔ντ) — evidence neutrinos have mass (Nobel 2015).

Open simulation →

Feynman Diagrams Giản đồ Feynman

The pictorial language of particle physics: lines and vertices for electrons exchanging photons, annihilation and β decay. A tool for computing probabilities.

Open simulation →

BEC Ngưng tụ Bose–Einstein

Cooled to nano-Kelvin, bosons pile into one quantum state becoming a ‘super-atom’ — the 5th state of matter. Compare Boson vs Fermion.

Open simulation →

Atomic Orbitals Số lượng tử & Orbital

A rotatable 3D electron probability cloud: s (sphere), p (dumbbell), d (cloverleaf). The four quantum numbers & the Aufbau filling order build the whole periodic table.
